We just released OctoPerf 18 and its main addition is a new load testing engine: K6. You can now import your K6 scripts and run them without changing a single line, next to JMeter and Playwright Virtual Users, in the same scenarios and the same reports. In this blog post I import a K6 script that browses our public demo shop, validate it, run it and go through the results. The scripts can be downloaded if you want to follow along. I will finish with the things that work differently than with JMeter.

Over-the-air (OTA) updates let you fix a bug in your React Native app and get it to users the very same day, without waiting for App Store or Google Play review. That speed is why teams adopt OTA.

And when you start thinking about properly modelling and handling them when the project is already in full swing, you are too late. Good errors can help reveal what works and what doesn't work.

To avoid duplicate Sidekiq jobs, you have three options: guard enqueues yourself with database flags or a queue scan, use Sidekiq Enterprise’s unique_for option, or add the free sidekiq-unique-jobs gem, which locks jobs in Redis by class and arguments. On Sidekiq 8, sidekiq-unique-jobs 8 with lock: :until_executed covers most cases.

Organic traffic usually drops for one of four reasons: a competitor took your rankings, keywords slipped out of the top 10, a technical issue appeared on your site, or you lost backlinks. Your SEO dashboard shows when the drop started. The reason sits in Semrush, split across Position Tracking, Organic Research, the backlink reports and the site audit. Finding it means opening four reports, exporting four files and lining them up against your traffic chart in a spreadsheet.
